Ghost sharks have evolved rows of true teeth on a bizarre forehead rod used for mating. Fossil and genetic evidence revealed the tenaculum’s teeth develop the same way as those inside the mouth, offering a striking example of evolution’s ability to repurpose biological tools. Ghost sharks have evolved rows of true teeth on a bizarre …

Meal timing shifts with age, and researchers found that eating breakfast later is tied to depression, fatigue, sleep problems, and an increased risk of death. Monitoring when meals are eaten could provide an easy health marker for aging adults. Meal timing shifts with age, and researchers found that eating breakfast later is tied to depression, …

Scientists have uncovered microbial DNA preserved in mammoth remains dating back more than one million years, revealing the oldest host-associated microbial DNA ever recovered. By sequencing nearly 500 specimens, the team identified ancient bacterial lineages—including some linked to modern elephant diseases—that coexisted with mammoths for hundreds of thousands of years. These discoveries shed light on …

A large Brazilian study following more than 12,000 middle-aged adults found that those consuming the most artificial sweeteners—commonly found in diet sodas, flavored waters, and processed snacks—experienced significantly faster declines in memory and thinking skills. The effect was equivalent to about 1.6 years of extra brain aging, with the strongest impact seen in people under …

Scientists have uncovered a surprising way Parkinson’s disease may start: tiny toxic proteins that punch holes in brain cells like revolving doors. Instead of causing instant collapse, these flickering pores slowly weaken the cells, which could explain the gradual onset of symptoms.

New research reveals that carbon made it possible for Earth’s molten core to freeze into a solid heart, stabilizing the magnetic field that protects our planet. Without it, Earth’s deep interior — and life above — might look very different. New research reveals that carbon made it possible for Earth’s molten core to freeze into …
